Did a bit more fiddling with the dev branch and this is the output I
get when I try to run the driver directly without using root.

And I just figured out what's causing it. It seems hotplug is doing
something funky to my usb /proc entries.

yuna usb # ls -l /proc/bus/usb/*/*
<snip>
-rw-r--r--  1 root root 52 Dec  3 16:50 /proc/bus/usb/003/006

FIX:
yuna usb # chmod 0666 /proc/bus/usb/003/006

---
yuna usb # ls -l /proc/bus/usb/*/*
